			15:23 < stuw__> marvin24, hi. I got uart data from nvec - http://pastebin.com/BnQkpQ6k
			15:24 < stuw__> I failed to solder a wire to nvec leg to sniff i2c :((
			16:50 < marvin24> stuw__: cool
			16:50 < marvin24> but what does it mean?
			16:55 < stuw__> marvin24, maybe some coded messages/statuses for debugging
			16:57 < marvin24> is this during power on?
			16:57 < stuw__> I'd like to sniff i2c bus on nvec and alc5632 + amp power rail
			16:57 < stuw__> marvin24, it's power on (android boot) + few codes from poweroff by power button
			16:59 < marvin24> ok
